I ordered my 7500 last Monday and recieved it today.It was shipped from MA.The 7500 is replacing the 7125 i got before Christmas.I only got to play with it a few hours tonite,but this amp has a tighter bass impact with better detail than the 7125.I have my fronts and rears crossed over @60hz and the center @80hz and on u-571 the amp ran very cool.My speakers were sounding to bright with the 7125,but with the 7500 the sound is fuller~the mid's and low end keep up with the highs now.I'm very pleased with the 7500 and it was well worth the extra $500.Note:The 7125 didn't have a ground on it's plug,the 7500 does and i had a problem with a ground loop from my cable box.
